Your giving this up for the European Union. Is that what you want? They do not proscribe to this law, in fact the opposite.
English law is simple, you can do what you want unless specifically prohibited.
European law, you can do “what is written in law” everything else that is not written in law, is prohibited.
I hope you understand the difference!
